"It's very important to me and my country to put my name into boxing history," said Manny Pacquiao today regarding his June 28th attempt to become the first Asian fighter to win four sanctioned world titles in as many different divisions when he challenges David Diaz for the WBC lightweight title. The Pacman says that he has maintained his speed, increased his strength and is very comfortable at the higher weight. "I believe that I'm stronger than him at 135 pounds," said Pacquiao, who revealed that he walks around between fights at 150 pounds. "I think I can fight at 140 pounds," he added.
